Using Piezoelectric Devices To Transmit Power Through Walls

It would not be necessary to make holes in walls for wires. A method denoted wireless acoustic- electric feedthrough (WAEF) has been conceived for transmitting power and/or data signals through walls or other solid objects made of a variety of elastic materials that could be electrically conductive or nonconductive. WAEF would make it unnecessary to use wires, optical fibers, tubes, or other discrete wall-penetrating signal-transmitting components, thereby eliminating the potential for structural weakening or leakage at such penetrations. Avoidance of such penetrations could be essential in some applications in which maintenance of pressure, vacuum, or chemical or biological isolation is required.

Self-Contained Therapeutic Thermal Wrap

A company seeks technology leading to a flexible, adhesive thermal patch or wrap for sore muscles that provides lasting warmth for 8 to 12 hours or more. The technology should not involve a chemical active in contact with the skin. The heating effect should be able to be activated anywhere, without the use of plugs or wires. It should provide perceivable relief from discomfort within about one minute, and fit comfortably over wrists or knees without being overly obtrusive.

Paracellular Drug Delivery Through Baker’s Yeast Microcapsules

Yeast has the ability to reversibly open up the junctions between cells to aid drug delivery. By micro-encapsulating active ingredients inside the yeast cells, this technology enhances paracellular movement of active ingredients in mucus-rich areas such as buccal, oral, nasal, vaginal, anal, and others. Application could be by means of powder, tablet, capsule, chewable tablet, chewing gum, melting film strip, spray, cream, or gel. Yeast offers an alternative to chitosan as a permeation enhancer and mucoadhesive mechanism.

High-Performance CIGS Solar Cell Saves Resources

AIST has developed a thin-film technology that can reduce the consumption of raw selenium below one-tenth of the conventional standard when manufacturing non-silicon-based copper-indium- gallium- selenide (CIGS) thin-film solar cells. The technology uses radio-frequency- cracked selenium radicals instead of conventional vaporized selenium, enhancing the conversion efficiency of a solar cell, and results in cells of reproducible quality from run to run. Additionally, the technology uses a black metal electrode and a light-absorbing layer containing zinc oxide. This brings about a great advancement for mass production of high-performance CIGS modules.

NASA Goddard Enters the World of Online Gaming

Researchers at NASA’s Goddard Space Flight Center in Greenbelt, MD, are on the verge of heading into a new virtual world for the good of education. The initiative is the result of an anticipated new Space Act Agreement (SAA) administered by Goddard’s Innovative Partnerships Program (IPP) Office. The Massively Multi-Player Online (MMO) Learning Game platform is a NASA-wide initiative managed at Goddard and administered by the Learning Technologies Project Office (LTPO). The project is designed to increase interest in, and pursuit of, science, technology, engineering, and mathematics (STEM) for middle school through higher education students.

Siemens PLM Software

Siemens PLM Software, Plano, TX, has introduced synchronous technology, a history-free, feature-based CAD modeling technology integrated into the company’s NX™ and Solid Edge® software. The technology simultaneously synchronizes geometry and rules through a decision- making inference engine. For design, it defines persistent dimensions, parameters, and design rules at the time of creation or edit, without the need for an ordered history. It also automates the implementation of planned or unplanned design changes in seconds, regardless of design orientation, and with or without a history tree. The technology allows users to reuse data from other CAD systems without remodeling. It also merges 2D and 3D environments, and automatically i8nfers common constraints and executes typical commands based on cursor position. For Free Info .
